Title: Adding an inexpensive 2nd display to a 898
Post by: SPLMAXSAM on August 09, 2012, 01:50:01 PM

I have a small 16 foot center console boat.  I fish on a great lake for walleye.  I use a humminbird 898 mounted in the center console for navigation and sonar.

When trolling, I often face the stern to watch the rods and cannot see the 898 si display screen .  I am very frugal (cheap).  So i wanted a display mounted in the stern that would display sonar.  Network feature and a second humminbird was out of my budget

After several reviews, I realized the best way to add a 2nd display, would be to use the VIDEO OUT feature of the 898.

I ordered the video cable from my humminbird dealer.  I had a small 7" LCD screen used in automotive application.  It is 12 volt and is pretty bright display.  They can be found on ebay for @$40 - $99. The screen is not designed for marine.   I also had a 16 foot RCA cable and some red/black power wire.

I wired the power ground to the same power ground wire as my humminbird.  I plugged in the video out cable into the back of the Humminbird.  I routed the cables to the stern.  I connected my test display.

Here is a video showing a test run

My next step is to paint the monitor housing light color (for heat) and to seal the housing for moisture

Sorry, I tried making the original post using my cell phone.  I was able to add some pictures and fix the link.

SPLMAXSAM, Looks like a great solution ..... Hope you can keep the water out.
I have experimented with this myself, but never have done a permanent mount.
